摘　　要：以Fe(NO_(3))_(3)∙_(9)H_(2)O和Bi(NO_(3))_(3)∙5H_(2)O为原料,采用水热法合成铁酸铋,对合成的样品进行XRD和SEM表征。以印染厂三级出水为研究对象,以废水的COD和苯胺浓度为指标,采用光芬顿方法,研究铁酸铋对废水的光降解性能,考察了废水初始pH、铁酸铋用量、H_(2)O_(2)用量和添加方式对铁酸铋光解性能的影响。结果表明,在初始pH为3、铁酸铋用量超过50 mg/mL、H_(2)O_(2)用量超过1 mL/50 mL(0.5 mL/50 mL)时,COD和苯胺的去除效果好;对于COD,H_(2)O_(2)分批添加的方式去除效果较好,但是对于苯胺,H_(2)O_(2)一次性添加方式去除效果好。Using Fe(NO_(3))_(3)∙_(9)H_(2)O and Bi(NO_(3))_(3)∙5H_(2)O as raw materials,bismuth ferrite was synthesized by hydrothermal method,and the samples were characterized by XRD and SEM.The photodegradation perfor-mance of bismuth ferrite on wastewater was studied by using the photofenton method with the COD and ani-line of wastewater as indexes.The effects of initial pH,the amount of bismuth ferrite,the amount of H_(2)O_(2) and the way of addition on the photolysis performance of bismuth ferrite were investigated.The results showed that when the initial pH was 3 and the amount of bismuth ferrite was more than 50 mg/mL,the amount of H_(2)O_(2) was more than 1 mL/50 mL(0.5 mL/50 mL),the removal effects of COD and aniline were both good.The effect of batch addition of H_(2)O_(2) for COD was better than that of single addition of H_(2)O_(2) for aniline.
